Mine is not as good as the others but here it goes.
My first was watching Star trek 2 when I was a child, seeing this technology on screen, showing me that we are not the only humans in the galaxy. After seeing it, I watched all the original series movies and then went on to TNG. I loved the show. It showed me that being different is ok, and living in an emotional abusive broken home myself, it was nice to see that things would get better. No hunger, disease, poverty (which ive struggled thru my entire life), no homelessness, etc. When i saw ds9 and voyager for the first time, it was amazing, the graphics were so much better and it seemed so real, that at times i had to tell myself that we are not that advanced. I always look at the medical part of it, being afraid of needles and always having to be stuck for something, i bawl at the sight of a needle and hate them with a passion, seeing that in the future needles were not needed for much anymore lets me know that one day it will happen. One day we will all be equal. (i wanted to add something to this but could not make it sound right, so i will end here)
